Facility Status at Thousand Islands National Park

Like many parts of the St. Lawrence River and Lake Ontario, significant flooding impacted the park in 2017 and many of the park’s public docks were damaged. We are in the process of rebuilding these docks so that boaters can continue to discover and enjoy the beauty of the islands.    

With visitor and staff safety the top priority, Parks Canada has brought in an engineering firm to fully assess the extent of dock damage. We are evaluating our mooring space and redesigning new docks for resilience against potential future flooding.  Significant repairs will continue throughout 2018 and are influenced by factors such as weather conditions, restrictions to protect spawning fish, and availability of contractors. 

We encourage boaters to plan their visit in advance by reviewing updates to the status of docks below.
